TolaZZ 'whom t may concern. Beit known that I, WILLIAM Ginsen- LnAr, a citizen of the UnitedStates of America, residingatPlymouth, in the county of Wayne and State of Michigan, have invented certain new` and useful improvements in Air-Guns, of which'the following'isa specification, reference being had therein to the accompanying drawings. c

Thisv invention relates to guns Aand refers more particularly to air guns or the like of that type in'which the `power for propelling the projectile is stored by compressing a spring or the like.

. ln guns of thetype above mentioned the projecting powerof the gun, which is governed by the powerstored when the` spring is under compression, isusomewhat limited by the fact thatthe work of compressing the spring by reciprocating the lever or thelike must not be beyond the strength of `the youth operating the gun. j l

The present invention contemplates a new and improved construction wherein thework ofstoringthe power is distributed throughout both the movements `ofthe lever or other reciprocating member. The invention also resides-in the novel constructionand mounting of the spring compressing and locking mechanism and in such other features of construction and arrangements and combiafter appear.

c ln the drawings: Y Y c Figure 1 is a longitudinal section through gun embodying my invention;

Fig. 2 is a viewsim'lar to Fig.y 1 showing Vnations ofpartsas will more'` fully hereinthe gun partly cocked;

Describing in detail the pai-acuer embodiment of my invention shown in the drawings, A designates the outer casing of the gun, B thefgun stock and C theinner or ltrue barrel which guides the shot or other projectile. T he gun illustrated in the drawings is of the type inV which there is employed apiston orl plunger D which is'drawn `Specification of Letters-Patent.

construction,and inthe present instance is' i provided with a projection D which telescopes within the true barrel C. rli`he shank F of the plunger is provided at its rear end with a latch member G which when drawn rearwardly slips over and latches with the searH and remains in this position until released by rocking the trigger l-I about its pivot H2. i

`For cooking the gun there is employed a lever l which is first rocked about its pivot `l forward to theposition shown in Fig.r 2 and then returned to its initial position, as shown in Fig. 3. ln order to permit ofthe use `of a relatively strong spring without exceeding the strength of the youthcocking l the gun, Vl have provided a novel arrangement wherein the force provided to compress the spring is divided between the forward and rearward movement of the reciprocating c member, such as the lever L ln detail the mechanism for accomplishing this purpose is as follows: At the forward end of the lever I there is pivotally connected at J a pair of links J which near their opposite ends are apertured at J2 to receive a cross pin J3 slidably mounted in an elongated slot F inV the shank F. This shank is preferably built up of spaced bars F2 and F3 and secured together by suitable securing members such as theV rivets F4 extending throughspacer mem bers F5. The forward part `of the lever is enlarged, as shown in Fig. l, and `has a bearing portion K to which thereis pivotally secured at K a pair of links K2. These links i at their rear ends are apertured at M to receive a cross pin H2 which extends through elongated slots M2 in the inner casing member N.- The, latter fits within the enlargement N of theouter casing `and is removably held in position by a` locking member .Atuits lower end the retaining memberf() Vhas an abutment'niember O2 between which and anabutment member,H3v onthe trigger there extends the usual trigger spring H4.

y In cooking the gun the parts operate as follows: I

Upon grasping" t'he hand gripping portion I2 the lever I is rocked forwardly about its pivot I. This will throw the forward end carrying the cross pin ,I upwardly and rearwardly and, through the action of the cross pin J3 on the abutment formed at the end of the slot F', willforcetheshank rearwardly, drawing with it the plunger and partly compressing the spring E. between the plunger Dy and the stationary abutment Q formed at the forward end of the inner casing member N. At the' Sametime the linksv Kgwill be drawn fswardv carrying with them the cross pin H2, the retain` ing member O, the trigg'erand scar member, these parts being moved vforward to the position shown in Fig. 2. At this point the latch member Gyride's over the sear member H, after which the trigger spring H* forces the scar upwardly intoulatched engagement. with the memberG. The shank of the piston or plunger D isA therefor-clocked to the scar and through the latter to the cross pin H2, at the end of the forward movement of the lever. However, yonly a' portion of the work of compressing the spring hasI been accomplished during this forward move'- ment, the remaining work being done upon the return movement of the lever to its ini*- tial position. At the start of the return movement the pin K is forced upwardly and rearwardly, which action, through the links K2 and cross pin H2, will carry the retaining member y(K) rearwardly with the trigger and scar member. Therefore, as the shank F of the plunger is locked to the scar the plunger will be further drawn rearwaruiy and complete the compression of the spring E. y l

It will be noticed that when the lever I is in thel position shownV in Fig. 2 it isv at a favorable angle for leverage, and I preferably utilize only theiirst portion of the return movement of the lever for 'completing the compression of the spring", ,thuis allowing an easy return of the lever to its initial position.

Frther as the pin Kvmoves by the line between the 'pins I and H2, the power of the spring is reversed in its action `with relation to the lever I and the latter is locked solidly against the stock, allowing the gun to remain cocked without beinglield.-

To fire the gun the trigger H is drawn in the usual manner, releasing the scar H from the latch member G and allowingthe spring E to force the plunger forward in the .usual manner;

The invention, however, is not necessarily limited to Storing the power in a compressed spring nor tothe use of alever 'as a reciprocating member. Thus in its broader aspects the invention would include a construction wherein a` sliding reciprocating member is employed,land various changes in the details of construction and arrangements and combinations of parts can be made within the scope of my invention.

What I claim as my invention is l. In a gun, the combination with a plunger, of a spring' against which said plunger is moved, a reciprocating member and means connecting said member with said plunger, vwhereby movement of said member in one direction will partially compress the spring, and the return movement of said member will complete the compressionl of said spring.

2. In a gun, the combination with a spring, of means for compressing said spring comprising a reciprocating member and a connection between said member and plunger to partially compress said spring upon the' forward movement of said member, and to further compress the spring upon the return movement of said member.

3. In a gun, the combination with a spring, of a stationary abutment at one end of said spring, a movable abutment at the other end of said spring, a reciprocating member and a connection between said reciprocating member and said movable abutment for moving the latter toward the stationary abutment upon movement of said reciprocating member in each direction.

4. In a gun, the combination with a spring, of a stationary abutment, a lever pivotetl to said stationary abutment, a plunger member and link connections between said lever and the plunger member, whereby forward movement of the lever will initially compress the spring and the return movement of the lever further compress the spring.

5. In a gun, the combination with a spring, of a plunger member and means for moving said plunger member against said spring to place the latter under compression comprising a lever, a link connected to said lever and having a connection with said plunger so as to move the plunger against the spring upon movement of the lever in one direction, andy a second link connected to said lever and having a connection with said plunger for moving the plunger to further compress the spring upon movcment of the lever in the opposite direction.

o. In a gun, the 'combination with a plunger and a spring, of a scar adapted tolock the plunger against the spring to hold the latter u'nder compression, a reciprocating member for bringing the scar into latching position upon its forward movement. and a connection between said lever and plunger for further compressing the spring after the plimger has been connected to the scar.

7. Y n gun, the combination with a casing, of a plunger movable therein, a Sear slidably mounted in said casing, and a lever having a connection with said plunger and sear for drawing said .parts toward each other upo-n movement of said lever in one direction and for drawing the sear and plunger in the same direction upon the return movement of the lever, and a spring adapted to be compressed bv the plunger upon movement of the lever in each direction.

8. In a gun, the combination with a casing, of a plunger having a shank movably mounted therein, a sear and a trigger also movably mounted in said casing, a spring adapted to be compressed upon movement of the plunger in one direction, and a reciprocating member`having a plurality of link connections with the plunger shank and the Sear, whereby'upon movement of the reciprocating member in one direction the sear and plunger are moved in opposite directions but toward eachother, while upon the return movement of the reciprocating member the sear and plunger are moved together in the same direction.

' 9. In a gun, the combination with a plunger and a casing having a stationary abutment, of a spring positioned between said Y abutment and plunger, a lever member having a link connection and a pin slidably mounted in the casing and adapted upon movement of the lever in one direction to draw the plunger toward the abutment, a Sear and releasing trigger slidably mounted in the'casing, a second link connection between said lever, sear and trigger whereby. the sear is advanced toward the plunger into latching engagement .therewith upon the first movement of the lever, and the sear re-v turned to its initial position upon return movement of the lever, said searcarrying with it the plunger so as to further compress the spring. f

In testimony whereof I aii'ix my signature.
